Unknown file extension for photos

by MarciaB / March 31, 2004 11:45 PM PST

I posted this yesterday in "graphics" forum .... thought I would try here, also Happy

I just received an expected e-mail attachment with some photos. The file extension is .pvm It is a new one to me and I have been unable to find it in any of my usual extension sites, such as I have several image viewing and editing programs at my disposal, and nothing is working. The only thing I could locate on this extension is the following:
PVM (Parallel Virtual Machine) is a software package that permits a heterogeneous collection of Unix and/or Windows computers hooked together by a network to be used as a single large parallel computer. Thus large computational problems can be solved more cost effectively by using the aggregate power and memory of many computers. The software is very portable. The source, which is available free thru netlib, has been compiled on everything from laptops to CRAYs.
That doesn't sound like what I would normally think of for image viewing - but then the more I read about it the more I realized it was WAY beyond what I do with computers!!

I can, of course (and probably will), contact the source of the photos and request a different format, but it's just "one of those things"........IOW driving me nuts!! LOL Does anyone here know of this extension? Is it maybe some software associated specifically with a certain camera?

TIA - and if I need to post in another forum with this, let me know.

Marcia, good to hear from you. Since I got into Linux and
avoid the attack dogs in Speak( I hate the loss of that forum). Sorry. I digress. Anyway, just a Google search shows that extension, although open source, was created for and is used for a particular project(pov-ray). So it's curious someone would send something to an outsider
with it. chuck

Hadn't gone to the site. Interesting. Of coarse, you could look for a player that will handle the extension. chuck

Hi, Marcia, have you tried changing the ..

file extension to .jpg on one of the photos to see if it would open in your browser? Or some other program. This hardly ever works but has on occassion for me.

Would this have anything to do with the photos that were created:

Sorry it took me awhile to get back to this thread!! I had almost forgotten about it! Silly me Happy

Anyway, as I had said originally, I also posted this in Graphics. Bob Profitt helped me, and betwixt the two of us we figured out what the problem was. The file extension had apparently been changed/renamed by the sender. It should have been .mpv, NOT .pvm. Anyway, it is for a Hewlett Packard program called Memories Disc Creator.

I decided it would be alot easier to just have her resend the pics to us with the generic format of .jpg than fool around with it anymore. I was "on a mission" to discover the extension/program issue - now that I have solved that to my satisfaction, I can just be lazy and have her send them again!! LOL

Was good to hear from you Chuck, and, again, thanks to both of you for your responses.
